' To all whont itflnay concern:

residing in the city and county of 'Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Fountains, of, which the following is a true and exact description, reference'being had to the accompanying drawings, which form'a part thereof. Y

My invention relates to the construction and operation of fountains provided with means for changing the visual effect either by regulation of a number of jets or by throwing colored lights upon the jets, or by both such means.

The object of my invention is, primarily, to

to vary visual effects with certainty and with speed; further objects ,of my invention beindividual jets of water and for controlling the various actuating devices of independent elements of the structure.

The nature of myimprovementswill be best understood as described in connection with Figure 1 is a diagrammatic view showing the nature of my device for arranging and throwing into operation different visual effec'ts in the operation of a fountain. Fig. 2 is an elevation, partly in central section, of

fluid to the actuating-cylinders. Fig. 3 isan elevation showing an alternative device which in some cases can be used in place of the cylinders and pistons for controlling the various units of the fountain system. Fig. 4 is a diagrammatic View showing in some detail the mechanism-which I prefer to use for controlling the various jets and mechanism which 'I prefer touse for controlling the light efiects.

Fig. 5 is a sectional elevation of part of a fountain equipped with my improvements. Fig. 6 is a plan View, partly in section, showing the valve controlling one of the supplypipes for'a spray-jet and'theactnating mechanism connected therewith. Fig. 7 is a plan view, partly in section, of one of the cylinjders used, for actuating the light-screens. Fig.

efficient means whereby ,cated, for instance at b 12 8 is a plan view showing one of the lightscreens and its actuating mechanism. Fig. 9 is an elevation, partly in section, on the line 9 9 of-Fig. 10, showing the construction of my preferred form of switches for controlling Fig. lOis an elevation, shown partly in section, on the line 10 10 of Fig. 9; and Fig. 11 isa perspective view of one of the switch-contact devices, (indicated at P P.)

Referring first to Fig. 5, A indicates the basin of the fountain, below which is formed a chamber A, separated from the basin by a roof A which forms the bottom of the-basin. and through which project light-tubes, as indicated at A A indicating an arc-lightsituated in the chamber A beneath the tube A and A a reflector, while A- indicates an ann'nlar jet-pipe surrounding the tube A the various individual elements of the 'system.

' B is a water-supply chamber situated in the chamber A and connected with a main, as

indicated at b, Fig. 1, the supply-chamber 13 having leading from ita series of pipes B B B &c'. each leading to one special jet devices-as, for instance, the pipe B leads to the jet device A. In each of the jet-supply pipes is situated a valve-chamber-as indi Figs. 1 and 5-and in each of these valve-chambers moves a valve, as indicated connected by rods 0 with pistons 0 moving in. cylinder 0 which are preferably for my purposes double-acting cylinders C and 0 indicating the ports leading into their oppo site ends and connecting through pipes D and D with supply-pipes D which conveniently lead from chambers D which are kept supplied with motive fluid, preferably air under compressionas, Fig. 1through a pipe D leading from an air-tank D supplied in turn through a pipe D through a compressor D actuated by a motor D Situated in each of the pipes D and D are valve-chambers, as indicatedat E and E These valve-chambers are provided with seats- E, E, and E the admission-port leading through'the seat E E andthe exhaust-port (indicated at 6 leading through thexvalveseat E". indicatesa'v at C, said valves being ioo alve adapted to alternately close said portsjand actuated through a stem thav ns'iter ahi b an electromagnetE, which acts to 'draw. the

- end of individual single-acting cylindersG G, &c., G, Fig. 1, indicating the connection, G a piston moving in the cylinder, Gr a pis ton-rd connecting throngh'a head G With. connecting-rods G which in turn are connected to the swinging lever H, pivoted at .H, supporting'at one. end the rim-H, holding a colored-glass screen h,- while at the other end of the lever is preferably arranged a counterweight, asindicated at H indicates a spring which normally re turns and holds the screen in the position indicated in Fig; 8, the action of the cylinder G being to move it to the position indicated in dotted lines in .the same figure, which position .is that lying immediately below, the light-tube A The controlling-valve in each of the pipes F is indicated ate, the valve being essentially the same, by preference, as

- that shown in Fig. 2 and already described.

I, Fig. 8, indicates the frameflupon which the cylinders G and levers H are'supported.

In Fig. 3 I have shown the valve rod'G' as having attach-ed to ,it an armature O situated between twoelectromagnets, (indicated at J and'J, and it is obvious that the valve rod and attached valve will be moved to open or close the valve, in accordance with which of the electromagnets is energized, just as the valve and valve-rod are moved in'the construct-ion shown in Fig. 6, in accordance with which end of the cylinder 0 is connected with the source of supply of the motive fluid,

The various electromagnetsarranged to actuate the diife'rent valves are each connected in a circuit controlled bya switch, in accordance with jhe movement of which the individual electromagnet is energized or deenergized, andzwhere the valves, suchasEand E, are used alternately the controllingswitch is preferably arranged to alternately encrgizeand deenergize the magnets appropriate .to said valves. Thus in Fig. l the circuit of the valve E is indicated bythe lines K, K, K and K and the circuit-wires of the valve E by the lines K, K Kfl'and K the line-wires K and K having terminals which are altere nately connected by a switch, as N, with the line-wire K leading through a switch L to "the line-wire K, which last-mentioned wire dependent and separate set of switches, (indicated at m and M,)-the connections being the position to couple the set of switches in- 'dicated at M M, 850., to arrange the second set of switches (indicated at 'm m) to produce any desired visual effect in the fountain, this effect being immediately brought into operation by simply changing the switch L, which cuts out the first set of switches and throws into operation the second.

\Vhere, as indicated in Fig. 5, a series of colored-light screens h is arranged beneath a single'light-tnbe A a single switch is conveniently employed, as indicated in Fig. 4 at Q, to energize at will any of the electromagnets governing the various valves 6 e, &c. the switch being turned to make contact with any of the terminals Q Q Q, &c., and the whole group controlled by the switch being indicated in the drawings by the'symbol M",

Where the double -acting cylinder controlled by independent electromagnetically actuated valves is employed, it is desirable to have some convenient device for regulating ,the degreeto which the valve controlling the water will open or. close, and such a device forms one element of my invention and is illustrated in Figs. 9, 10, and 4, the switch as I a whole being indicated inFig. 4 by the symbol M and each of the line-wires, as K and K, leading to it having the terminals, as indicated at O and P, N indicating the switch pivoted at N and having oppositely-disposed blades N N by which as the switchis moved in one direction'orthe other contact is made with one ofthe terminals 0, the circuit being completed through the switch N bymeans of asegment N and a spring-terminal of the line-wire K, as shown in Fig. 10. The upper partot' theswitch-lever (indicated at N) has a handle N, by which it is moved, said handle being, as, shown'in Fig. 10, separable from the switch and the upper-part'of the switch being'hollow, as indicated'at N", and having 'on each side of it spring-plates N N supporting contact devices N .N, from the backs of which project pins N, which extend into the opening N as shown. The handle N has an-opening extending through it, as indicated at N, in which issituated the sliding rod N having the head N at its top and the cone (indicated at N") near its bottom, said cone being lll'POSllilOll toact upon the pins N and the rod and cone being normallyheld in their upper positions by the action of aspring N pressing against a disk N at the end of the rod N The movement of the switch-lever to make contact with one of the terminals 0 does not make contact with either of the terminals P; but when such contact is desired the operator presses down upon the head of the rod N pushing out the terminals N and N into position to make con contact is made I a a connected with the linewires k and 70 will be .energized,'and thus tact with the terminal Pf, toward which the switch-lever is, and obviously wheneverthis both of the .electromagnets the motive fluid introduced to both ,endsof the double-acting cylinder and the exhaust from both ends out 01f. y In this way the motion lingvalve to open or close can be arrested at will andthe energy of the jet thus-modified." Having now described myinvention, what of the water-control- I I claim as new,an'dd esire to secure by Letters Patent, isv 1 '1'. In combination with a fountain havinga series of electromagnetic devices for changing the visual effect produced during its operation,'two sets of switches connected in mu1ti-,

ple with said devices and one switch oif e ach set connected to'actuate oneofthe electromagnetic devices in one direction or the other 1 in accordance with the position of said switch,

a generator having one'pole connected to all the actuating devices and a switch whereby the other pole'of the generator can nected with either set of switches at will, all

be consnbstantially as described, and so that any desired eifect can be set up on the disconnected .set of switches and brought into effect shifting the governing-switch. r

2.- In a combination with afountain having a series of water-pipes leading to jets and independently} actuatable valves forlcontrol ling the passage of water through said pipes,

means-for actuating said valves consisting of a ton acting on the valve,

7 admission and exhaust adouble-acting cylinder and piston, said pisvalves controlling the of the actuating fluid tothe ends of the cylinder, means for actuating said cylinder-valves, a slitting switch whereby said valves are alternately openedand closed and an independently-actuated' switching device whereby in pendentlv-actuatable' valves for magnet arranged to actuate each electromagnetic mission and exhaust of the actuatingfluid to the ends of the cylinder, electromagnetic means for actuating said cylinder-valves,-.a

shifting-switch whereby said valves are alternately opened and closed and an independently-actuated switching device connected and moving also with the shifting switch -whereby in either position of the shifting switch the closed valve can be opened and fluid admitted to both ends of the valve-actuating cylinder to arrest the piston in any desired position.

4. In combination with a fountain having a number of cylinders and pistons arranged to actuate devices for producing different visual efEects,-valve-casings, asE, having oppositelydisposed seats E E? and an exhaust-passage,

as e*, one or more of said casings being con nected in the motive-fluid conduit or conduits of each cylinder, avalve, as E adapted to alternately open and close the admission and exhaust passages-in each casing,

I an electroe said valve and'a series of switches controlling said elec= 'tromagnets as described.
